A high precision angle compensation controller for dish solar tracker installed on a moving large ship

The tracker has two axes, X-Y Cartesian mechanical system to compensate the roll and pitch of the ship movement. The system uses four light sensors in obtaining the highest intensity to adjust the dish for pointing the sun position. A system simulator prototype was built to verify the proposed system. Gyrometers are placed on the ship simulator and dish to monitor the focus of the angle system. Result for the prototype shows that the control system is capable to track the sun under ship movement. The error of focus angle is under 3.707 percent error of roll and pitch disturbances.
